will using it help prolongue battery life? help prevent build up of dust etc? i cleaned my laptop fully after disassembling as much as i could...would adding arctic paste be worth it? or am i likely to screw it up?

Also, any other recommendations on how to pimp out my m11xr2? im planning on trying to make it a completely anonymous laptop as much as possible with encryption, VPNs, TOR etc so was wondering whether i should be buying one of those WWAN cards? perhaps mini pci-e to USB adapter to the WWAN slot? im still new to all this and just beginning to read up so sorry if stupid question.

Also trying to find some cool skins but alas only ebay seems to be the answer?

you know what, i think i assumed it was my m11x r2 but now that i think about it, i could have been using my m18xr2 backup image i made.
have i really screwed up? is this going to affect my laptop/performance somehow?
